Analogue systems

Hello,

I just recieved my rs15 case and I put a couple of doepfer style VCOs
into th case and I can hear one VCO's output (faintly) through the
other's output (no patches). This shouldn't be happening. Does it
happen for anyone else? Is there also crosstalk when using the ASys
power connectors?

I wonder if the doepfer racks have this problem at all.
